Windows Update customers were recently affected by a network infrastructure event on January 29, 2019 (21:00 UTC), caused by an external DNS service provider’s global outage. A software update to the external provider’s DNS servers resulted in the distribution of corrupted DNS records that affected connectivity to the Windows Update service. The DNS records were restored by January 30, 2019 (00:10 UTC), and the majority of local Internet Service Providers (ISP) have refreshed their DNS servers and customer services have been restored.

While this was not an issue with Microsoft’s services, we take any service disruption for our customers seriously. We will work with partners to better understand this so we can provide higher quality service in the future even across diverse global network providers.

If you are still unable to connect to Windows Update services due to this problem, please contact your local ISP or network administrator. You can also refer to our new KB4493784 for more information to determine if your network is affected, and to provide your local ISP or network administrator with additional information to assist you.
